## Description

- description: The sluggish kinetics of oxygen evolution reaction (OER) are bottlenecks
    to develop hydrogen energy based on water electrolysis, which can be significantly
    improved using high performance catalyst. In this context, the CoNi layered double
    hydroxide (LDH)/Ti3C2 heterostructures are obtained using electrostatic attraction
    of the positively charged LDH and negatively charged Ti3C2 nanosheets as catalyst
    to optimize the OER　performance. Such alternately stacking exhibits good catalytic
    activity with a lower overpotential and a small Tafel slope, outperforming their
    individual components. The results by density functional theory (DFT) simulation
    find that the charge transfers from Ti3C2 to CoNi LDH, not only adjust the electron
    distribution, but also increase the electron density of the interfacial active
    sites, thus enhances the electron transfer efficiency inside the heterostructures.
    Moreover, the cobalt and nickel ions exhibit a synergistic effect in supplying
    more electrons to adsorb the adjacent intermediates with the active hydrogen and
    oxygen vacancies, to improve the adsorption capability and reduce the reaction
    energy barriers. These findings provide a rewarding avenue towards the design
    of highly efficient electrocatalysts for OER.
